Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a winding machine for a film or the like, and more particularly to a multi-axis linear motion winding machine for winding a film or the like without using a turret.

[0002]

2. Description of the Related Art A film or the like sent from a film forming process is wound on a winding core. When a certain winding length is wound, a new winding core is transferred from the wound core to the next new winding core. Rewinding is performed. In this case, conventionally, as shown in FIG. 4, the full winding shaft and the new winding core are usually installed on a turret of two axes A and B or a turret of multiple axes T. You are rewinding.

That is, FIG. 4A shows a state in which a new winding core is mounted on the B-axis while being wound on the A-axis, and the film F is wound on the A-axis by the contact pressure of the touch roller 7 via the guide roller. ing. Then, when the core of the A-axis is almost fully wound, the turret T turns, and when the state of FIG. 4B is reached and the new core of the B-axis reaches the winding position, the cutting blade 9 descends. The film is cut between the A-axis and the B-axis, the cut film is wound around a new core of the B-axis, and the winding of the A-axis is stopped. (See FIG. 4c)

[0004] When the winding starts on the new core of the B axis, a new core is mounted on the A axis (Fig. 4d).
), The conventional turret type winding process is completed, and rewinding is performed.

[0005]

However, in winding in which rewinding is performed using the above turret disk, the turret disk is determined between the winding cores according to the winding diameter. growing. Therefore, the size of the machine must be increased in accordance with the winding diameter, and the manufacturing cost increases significantly.

Further, when the distance between the winding shafts is increased, the distance between the film paths at the time of rewinding becomes longer, and a stretchable film or the like causes neck-in or wrinkles. Furthermore, when the distance between the winding shafts is large, the distance of movement of the core by turning the turret at the time of rewinding is large, making it difficult to perform short-cycle rewinding.

On the other hand, on the power transmission surface, in the turret disc system, since the take-up shaft is in the turret disc, a take-up motor is provided for each axis outside the take-up frame, and the original shaft portion of the turret disc that rotates is moved. Since it is necessary to relay power to the take-up shaft through relaying, the size of the transmission device becomes large, the rotational mechanical loss is large, and there is a major problem in controlling the transmission torque required for the take-up shaft.

The present invention addresses the actual situation of the conventional winding machine as described above, and focuses on a winding machine different from that of the turret type, and moves linearly independently in the front-rear direction and the vertical direction independently of each other within a range that does not interfere with each other. By finding a mold winder, the transmission can be simplified to eliminate the occurrence of mechanical loss, and even for easily stretchable films, the distance between the film paths during rewinding is extremely short, and film neck-in and film wrinkling can occur. It is an object of the present invention to provide a winding machine which prevents the rewinding cycle and further significantly reduces the rewinding cycle.

[0009]

That is, the winder according to the present invention, which meets the above-mentioned object, has at least upper and lower main frames disposed on the left and right at a required interval, and is provided on the upper frame of the main frame. Is provided with an upper take-up frame provided with a gripping portion of the upper take-up shaft so as to be vertically movable so as to be slidable in the front-rear direction at least between the take-up position and the full take-up position along the upper frame. On the other hand, the lower frame is provided with a lower take-up frame provided with a gripper for the lower take-up shaft so as to be able to move up and down in the vertical direction. The upper and lower winding frames and the upper and lower winding shaft grips are slidably arranged upward and can be moved back and forth and up and down independently without interfering with each other. , A cutting blade is arranged, and when full, one full roll is shifted from the winding position to the unloading position, the other winding shaft is shifted to the winding position, and the winding core is attached, and the full roll is attached. This is a two-axis linear motion type winder configured to cut a film between a new winding core and a cutting edge and wind a cut end on a running side around the new winding core.

[0010]

The winding machine according to the present invention is wound according to the following operation. First, the winding machine is different from the turret type, in which the two winding shafts are divided into upper, lower or front and rear portions, and travel independently in the front and rear directions and in the vertical ascending and descending directions within a range where they do not interfere with each other. And the operation at the time of rewinding is
For example, during winding with the lower winding shaft, the upper winding shaft grips the next winding core, and when the lower winding shaft reaches full winding, the lower winding shaft retracts, and the winding core of the upper winding shaft. Cuts the film, which comes into contact with the film and separates from the core of the lower winding shaft, by a cutting blade separately provided in the vicinity, winds one of them around the core of the upper winding shaft, and winds the terminal at the lower winding position. Wrap around the core of the shaft.

Thus, the wound core of the wound lower winding shaft moves within a range in which the new winding core of the next upper winding shaft can move to the winding position so that the next cutting can be performed. Then, the cutting of the film by the cutting blade and the winding of the upper winding shaft around the winding core are stopped, and the winding of the lower winding shaft is stopped.

Next, the process proceeds to winding by the upper winding shaft, and the same operation is repeated in a state where the upper winding shaft and the lower winding shaft are exchanged. Subsequently, winding by the lower winding shaft is continued. The film which is continuously fed by repeating the take-up and the take-up by the upper take-up shaft is continuously taken up on the core.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a schematic side view showing an example of a winder according to the present invention, and FIG. 2 is an explanatory diagram of a drive system of the winder, showing a drive system of a lower winding frame portion. In these figures,
Reference numerals 1, 1 'denote upper and lower main frames, which are integrally formed as a rectangular frame in the figure, are disposed to face left and right at a required interval, and linear rails 2 are provided on inner surfaces of the left and right main frames. , 2 ′ are provided, and the upper winding frame 3 and the lower winding frame 3 ′ are connected by the linear rails 2, 2 ′ at least to the winding position on the left side of FIG. , Which can be slid forward and backward between a full unwinding position on the right side, while the latter is disposed along the lower main frame 1 ′ at least in the winding position on the left in FIG. It is arranged upward so as to be able to slide back and forth between the full unwinding position.

The upper and lower winding frames 3,
3 'has a linear rail 11 on one side, that is, on the front side.
There is provided, comprising a winding chuck 10 for gripping the end portion of the upper winding shaft 4 and the lower winding shaft 4 'and having a take-up motor M ₃ as shown partially in each Figure 2 Each of the winding shaft grips 6, 6 'can be vertically moved up and down along the winding frame 3, 3' by the linear rail 11.
Is attached.

The movement of the upper and lower winding frames 3, 3 'and the upper and lower winding shaft grips 6, 6' in the front-rear direction and the vertical direction is exemplified by the lower winding frame in FIG. Each winding frame 3 ′ has a screw rod 13 and the screw rod 1.
By using a nut 14 through which the nut 3 is inserted, the nut 14 is attached to the winding frame 3 ′, and the screw rod 13 is rotated by the winding frame traveling motor M _{1 using the} screw gear 12 as a relay. The winding frame 3 'is slid within a required distance range.

Meanwhile, the upper and lower movement of each winding shaft gripper screw gear 17, 19 and the spline shaft 18, by a series of mechanisms consisting of nut 21 and the screw rod 20, the rotation of the motor _{M 2} first screw gear 17 And the spline shaft 18 and the second screw gear 19 are sequentially rotated, and the winding shaft gripper 6 ′ with the nut 21 attached thereto via the screw rod 20 and the nut 21 is moved up and down within a required distance range. It has become.
However, needless to say, the above-mentioned sliding and lifting mechanism is not limited to this, and another driving mechanism may be used as appropriate. Although the above description has been made based on the lower take-up frame shown in FIG. 2, the upper take-up frame is substantially the same, although there is a vertical difference.

In the above configuration, the operation of each of the upper and lower winding frames and each of the winding shaft gripping portions can be performed independently in FIG. 1 without interfering with each other in the operation in the front-rear direction and the vertical direction at the time of rewinding. It is designed to be In FIG. 1, reference numerals 7 and 8 denote touch rollers provided in the vicinity of a winding position. A first touch roller 7 takes up a film F to be fed, and in the figure, a lower winding shaft 4 '.
The second touch roller 8 is a roller that presses and transfers when a roll R that is almost fully wound at the winding position is moved, and is usually a second touch roller. A cutting blade 9 for cutting the film is provided between the winding shaft 8 and the winding shaft 4 '. Thus, in the winding machine of the present invention, unlike the rotation of the turret board, the two winding shafts are divided into upper and lower parts and front and rear parts, and do not interfere with each other so as to go straight in the front and rear direction and the vertical direction to perform rewinding.

FIGS. 3A to 3I sequentially show the mode of the rewinding operation when the film is wound by the winder according to the present invention, and FIG. 3A shows the lower winding shaft gripper 6 '. The first touch roller 7 is brought into pressure contact with the winding shaft 4 ′ so that the film F
Is being wound, the cutting blade 9 is positioned above, and the upper winding shaft gripper 6 stands by above the lower winding shaft gripper 6 ′ without interference.

In FIG. 2B, the film is substantially fully wound around the core of the lower take-up shaft 4 'and moves rearward, and at the same time, the upper take-up shaft 4 which has been located above is lowered and the core is mounted. State. Thereafter, the lower take-up shaft 4 'continuously performs take-up, and the upper take-up shaft 4 is located at the winding position (Fig. C).
And the cutting blade 9 descends between the full roll R and the new winding core at the winding position as shown in FIG.
The cut end is wound around a new winding core of the upper winding shaft 4, and the end of the full roll is pressed against the roll to stop winding.

Then, winding is continued on the upper winding shaft 4 side (FIG. 5E), and when the upper winding shaft side is almost full, the winding shaft 4 moves backward (FIG. 5F). At this time, the lower take-up shaft 4 'from which the full roll R has been discharged returns to the standby position, and a new core is attached.

In this way, the upper winding shaft 4 retracts while winding, and the lower winding shaft 4 'has a new winding core and rises to the winding position (FIG. 7G). The cutting blade 9 descends between the full roll R on the take-up shaft 4 side and the core on the lower take-up shaft 4 'side to cut the film of this portion, and cuts the cut end of the running film side to the lower stage. While the roll is wound around the winding core of the winding shaft 4 ', the cut end of the full roll is pressed against the roll, and the winding of the upper winding shaft 4 is stopped (Fig. H).

In the above sequence, a series of rewinding operations is completed, and when the lower winding shaft 4 'is almost full, the upper winding shaft gripper 6 is in the standby position and returns to the initial state shown in FIG. Returning, this is repeated thereafter, and rewinding is performed continuously.

Since the winding machine of the present invention performs the above-described rewinding operation, the drive system is greatly simplified as compared with the above-described conventional turret board system. This will be further described in detail with reference to FIGS. 5 and 6. When the winding diameter is the maximum diameter, the distance between the winding shafts at the time of cutting and rewinding is turret type (FIG. 5b) as shown in FIGS. in is a distance L ₂ that is determined, only it needs only independent movement distance L ₁ necessary for the present invention winder (a diagram), the cutting rewinding. For example, in FIG. 6, l ₁ ; interval necessary for cutting l ₂ ; dimension without interference between the maximum winding diameter and the central axis of the turret machine T d; core outer diameter D; maximum winding diameter L ₁ = D / 2 + D / 2 + l ₁ , L ₂ = 2 (l
₂ + D / 2). For example, l ₁ = 100 mm, l ₂ =
Assuming that 100 mm, d = 90 mm, and D = 1200 mm, L ₁ = 90/2 + 1200/2 + 100 = 745 mm L ₂ = 2 (100 + 1200/2) = 1400 mm

That is, the distance between the new winding core and the full winding shaft core at the time of rewinding is greatly reduced to 1745 mm in the turret type and 745 mm in the direct acting type of the present invention. Further, when the winding diameter is small but the maximum diameter Figure 5c, the winding shaft winding center distance L ₂ in the turret plate formula (b diagram) as shown in d is not changed, the present invention linear type (a because varied according to the figure) the withdrawal distance winding diameter, the distance required for cutting, can stop at a dimension position of l ₁ in FIG. 6, and Aramaki core, is much the film path distance between full reel Can be shortened.

[0026] This means that in a film or the like which is easily stretched,
Since the interval between the film passes at the time of rewinding is very short and the neck-in of the film and the wrinkling of the film can be prevented, the rewinding cycle is short and the cost is greatly reduced because the machine is compactly assembled. Especially large diameter (1500 ~
This effect is large in winding up to 2000 mm)
Significant cost reduction.

As shown in FIG. 6, in the conventional turret machine system, since the winding shafts A and B are located on the turret machine T,
As shown in FIG. 7, it is necessary to install a winding motor M for each axis on the outside of the winding frame and relay the power to the winding shaft by relaying the original shaft of the rotating turret board T. However, in the direct-acting type winder of the present invention, the winding shaft is directly attached to the winding frame 3, 3 '.
It is possible to attach the take-up motor M _3, the transmission from the take-up motor to the winding shaft small simple, becomes a structure that most mechanical loss does not occur, it is possible to control the winding torque with high accuracy.

Further, as shown in FIG. 7B, the turret board system is configured such that an air pipe and various sensors mounted in the turret board T are passed through a turret base shaft having one end of a worm gear 31 for turning, and a slip ring is provided. 33 and a rotary joint 32, etc., it is necessary to connect to the outside. However, in the method of the present invention, since the upper winding shaft and the lower winding shaft do not cross each other, as shown in FIG. It can be directly connected to wiring lines and pipes from 3, 3 ', which enables simplification and drastic cost reduction.

As described above, the direct acting winder according to the present invention is a revolutionary winder having many advantages over the conventional turret machine. In the above description, the description has been given based on one embodiment of the winding machine of the present invention. However, it is needless to say that various modifications can be made to the detailed structure.

[0030]

As described above, according to the present invention, in a winding machine for a film or the like, the winding shaft gripping portions are independently provided vertically and longitudinally, and the two winding shafts do not interfere with each other in the longitudinal direction and the vertical direction. The film can be moved straight forward within the range, and the continuously fed film can be cut from the full axis to the new axis and re-wound. Unlike the method using the conventional turret board, the winding frame is moved forward and backward, up and down and up and down. To go straight to
The following various remarkable effects are obtained as compared with the conventional turret type.

(1) The distance between the winding cores is 分 of the diameter of the maximum winding diameter, but is less than half of the turret type. Further, the distance between the winding cores may be only the dimension required for cutting the film between the new winding core and the outer periphery of the full roll, and the film path length is constant regardless of the winding diameter. Therefore, the moving distance of the winding shaft is short, the size of the machine is small, and the length between the film paths at the time of rewinding is short, so that the wrinkles and shrinkage of the film are also small. Further, since the moving distance of the winding shaft is short, there is an advantage that the moving time is short and the rewind cycle time can be shortened.

(2) The take-up shafts are provided independently in the upper and lower stages, and the respective take-up motors can be attached to the take-up frame. Therefore, the drive system is simple and the mechanical loss is very low. Since it is smaller, the accuracy of winding torque control is improved. Also, because of the above structure, the motor, sensor, air pipe, and the like required for the winding shaft portion do not interfere with the upper and lower stages, so that wiring and piping can be performed independently, and there is no need to use a slip ring or the like. Thus, the manufacturing cost can be greatly reduced in comparison with the turret type based on the above-described respective configurations.
